This invention relates to mechanism for; supporting a spraying device and also the article to be sprayed, one object of the invention being the provision of means whereby the spraying device may be manually moved on horizontal guides and said horizontal guides raised and lowered on vertical guide members.

A further object of the provision of means whereby movable carriage may be 100 cal guide members by bolts extending into sockets in said guide members.

Another object is the provision of means whereby said vertical guide members may be rotated about their axes to place new sets hf bolt sockets in position to enact with the invention is the the vertically locking bolts of said carriage, each guide member having a plurality of vertical sets of sockets, thesockets in each vertical set being spaced apart diiferently from those of the other sets.

Yet another object of the invention is the provision of means whereby the articleto be sprayed may be disposed at different dis tances from the rear of the main frame carrying the spraying device.

These objects and others are attained by the mechanism illustrated in the accompanying drawings.

For the purpose of illustrating the inveni base 10, this member belng threaded to the tion, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, al-' though it is to be understood that the various instrumentalities of which the invention consists can bevariously arranged and or ganized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the appended claims.

Similar characters indicate 2 like parts throughout the several figures of the drawsecured to'the floor and tied together by a bar 11.

Each base 10 has an n wardly extending hub 12 in which is revo ubly mounted the lower end 14 of a vertical guide member 13 which is preferably cylindrical with said lower end 14 reduced in diameter.

in s. Tn the drawings 10, '10 are bases preferably Figure 9 represents a vertical'section on The lower end 14; is provided with a plu rality of depressions 15 e uallyspaced inthe same horizontal plane a out the periphery thereof. t v

A locking member 16 is provided for each hub 11 and having a reduced end 16* adapted to enter a depression 15 and retain said guide about its axis.

.90 member in position when it has been adjusted Each guide member has aplurality of veri tical sets of radial sockets 17 formed therein, the sockets 17 of each vertical set being equally spaced apart and the spacing of the sockets in each set varying from the spacing of the sockets in each of the other sets.

Pinned to each guide member 13 are two collars 18 between which is disposed ahub 19 of abracket 20 extending rearwardly from said guide member 13.

The brackets 20 of the two guide members 13 are tied together by rods 21 and 22 and.

from the rod 22 extend struts 23 the lower end of each of which is connected at 24 to an ear 25 formed upon a base 10.

' Extendin are a plura ity of spaced pins 26 between which a frame 27 is adapted to be positioned.

This frame may be of any desired construcupwardly fromvthe bracket 20 tion but'preferably is made of a wood panel with its edges enclosed in metal as indicated at 28.

To the wooden panel 27 may be secured in any well known manner a hide 29 or other article to which it is desired to apply a spray of igment.

' annular peripheral groove 35 into which extends the reduced end of the threaded member 36, thereby placement guide member 13. Y

The hub 31 is also provided at the front and rear thereof with ears 37 from which braces 38 extend upwardly at an angle to the ceiling freventing the accidental diswhere their upper ends are fixedly secured in position.

The hub 31 also has ears 39 extending upwardly therefrom between which are disposed respondin grooved rollers 40 revoluble about pins 41 positioned in said ears 39.

Beneath each hub 31 is a collar 42 inned to the guide member 13 and between t e collar 42 and the hub'31 is a hub 43 having a rearwardly extending arm- 44' provided with a plurality of downwardly extending pins 45 corresponding in number with and oppositely disposed to the pins 26 on bracket 20.

These pins 45 serve as guides for the upper end of the frame 27.

The frame 27 may be disposed between corairs of pins 26-45 to vary the distance 0 t e frame 27 from the rear of the vertical guide members 13.

The two arms 44 are tied togetherat their outer ends by the rod 46 and each arm 44 has riveted thereto at 47 a bar 48, the opposite end of which is riveted to the an le iron 33 at 49. By the construction descri d a rigid front framework is provided which has mounted thereon means whereby the article to be sprayed may be positioned at various distances from the rear of said framework. Extending over each pair of rollers 40 is a flexible member 50 to one end of which is secured a weight 51 while the opposite end is secured to a roller carrying member 52, each end of which is bifurcated and provided with a pin 53 on which .is revolubly mounted a roller 54.

The rollers 54 have peri heral grooves fitting the peripheries of t e vertical guide members 13 over which they are adapted to travel.

Each member 52 is provided with two depressions 55 in which rest the ends of the the hub 31 from the vertical tubes 56 and the two members 52 are tied togzther by the rods 57 extending through the tu s 56 thus forming a rigid carriage ada ted to be moved freely lengthwise of the guide members 13 and carry therewith a spraying device.

Each member 52 is provided with ahub 58 through which extends a locking bolt 59, the outer end of which is adapted to enter a socket 17 and lock the carriage from vertical movement.

The bolt 59 has a collar 60 pinned thereto against which the spring 61 acts to force the bolt outwardly, the outward movement being limited by the collar 62 pinned to said bolt and normally contacting with the end of the hub 58. V

The inner end of each bolt 59 is provided with a (perforated head 63 to which is secured one en of a flexible member 64 which member 64 extends through an opening 65 in a spider 66 forming a support for the spraying device 67 only a portion of which including the nozzle 68 is indicated in the drawings.

As the spraying device itself forms no part of the present invention it is deemed unnecessary to illustrate the same in detail.

The spider 66 is preferably rovided wit four pairs of legs the outer en s of each pair having mounted therein a pin 69 on which revolves a roller 70.

Each roller 7 O is provided with a peripheral groove fitting the periphery of a tube 56 along which the support 66 is adapted to travel horizontally.

The spider or su port 66 has a downward extension 71 provi ed with a vertical socket in which is rotatably mounted a in 72 having an annular groove 73 into which extends the end of a screw 74 threaded to said extension.

This pin 72 is part of the spraying device holder 75 which is made in two arts, the part 76 being removable to permit the positioning of the member 77 and hook 78 of the spraying device 67 between 'said parts 75, 76. When thus positioned these members are clamped between said parts 75, 76 by means of the screws 79 and nuts 80. r

The hook 78 partially surrounds the hubs 81 formed upon the two parts 75, 76 of the sprayin device holder. The spra ing de-- vice hol er may be oscillated manua 1y about the axis of pin 72.

In using this s raying device the hide 29 or other article to sprayed is properly positioned at the rear of the main framework and the spraying device 67 is positioned at the top of the hide with the bolts 59 in two of the sockets 17.

' The support 66 is then moved horizontally along the tubes 56 with the spraying device 67 in commission and an even distribution of spray in a. straight path will result.

The operator then by means of the flexible member 64 releases the bolts 59 from said tically movable carriage.

sockets 17- and'moves the carriage down wardly to permit the bolts to engage with the next lower sockets 18 and the horizontal movement of the spraying device is repeated.

The weights 51 are so constructed as to counterbalance the weight of the vertically movable carriage and the parts supported thereby.

If it is desired to vary of the vertically movab e carriage the operator releases the locking members 16 and rotates both of the vertical guide members untilother and similar sets of sockets .17 are in position to coact with the bolts 59 of the ver Any usual means for indicating the proper adjustment of the rotatable vertical. guide members 13 may be used.

By the use of this improved spraying machine an even distribution of pigment may be deposited over the entire surface ofthe article being treated and this distribution may be varied at the will of the operator. 1

Heretofore, where pigments have been ap- 26 .plied by an air brush held in the hand of the operator the operator soon becomes very tired and has to rest. I

Moreover, when the pigment is thus applied it is impossible for the operator to so direct the air 'brush'as to give an even distribution of the pigment and the hide when treated has a very streaked appearance. as a consequence.

This objection is wholly overcome by usingadvantages of the invention will be well understood without further description.

Having thus described my invention,-I'
